CEPIS Warns EU Against “Backdoor” Chat Monitoring in Child Protection Debate

Council of European Professional Informatics Societies (CEPIS) has warned EU policymakers against proposals it says could introduce broad monitoring of private communications under the banner of child protection. In a statement dated June 26, 2026, CEPIS cautioned that discussions around digital child protection rules may be moving toward policy outcomes that resemble mass surveillance—potentially including warrantless access to private communications such as messages, emails, and cloud content.

CEPIS argued that ongoing consultation discussions risk undermining earlier safeguards and political positions that rejected blanket scanning of chat services. It said signs of possible political reversal could shift the approach from targeted enforcement to systems that would require wide-scale detection and monitoring, with serious consequences for fundamental rights, cybersecurity, and democratic transparency.

At the center of CEPIS’s concern is what it describes as policy “reversal” and “backdoor” monitoring: even if the mechanisms are framed as voluntary, CEPIS says they could become effectively mandatory if messaging providers are pushed to adopt scanning to comply with regulatory requirements. The group also warned that such approaches could weaken encryption and potentially lead to broader impacts well beyond the originally intended child-protection use case.

CEPIS highlighted multiple risks it says should stop the proposals from advancing in their current direction:

de facto mandatory monitoring rather than targeted measures insufficient judicial oversight for detection actions increased barriers for private communication through requirements such as identity or age verification

The group also argued that automated detection technologies have technical limitations, including the risk of false positives that could flag legitimate communications, while sophisticated offenders may evade detection by switching tools or platforms. CEPIS said the overall effect of mass scanning would likely fall disproportionately on ordinary users rather than reliably disrupting abuse networks.

CEPIS urged EU institutions to focus on alternatives it considers more effective and lawful, including increased investment in specialized investigative units, faster analysis of credible leads, stronger cross-border law-enforcement cooperation, and improved support for victims. It also called out concerns that previously rejected measures could be resurfaced through procedural tactics, warning that bypassing parliamentary decisions would damage trust in EU lawmaking.
